TRACK CHAIN BOGIE OF CARRIAGES Filed Sept. 24, 1929 jni 'erzfor lan e I 5 Patented Apr. 26, 1932 UNITED STATES PATENT OFFICE ADOLF LANGE, OF LUBECK, GERMANY, ASSIGNOR TO L'I'IIBEGKER MABGHINENBAU- GESELLSCHAFT, OF IaUBECK, GERMANY TRACK-CHAIN 120cm or caaamaas Application filed September 24, 1929, Serial No. 394,908, and in Germany October 22, T928.

My invention relates to track-chain bogies of carriages or cars with two or more trackchain guiding frames, and more particularly to an improved controlling mechanism for or in connection with the bogie or truck.

Track-chain bogies or trucks of the kind referred to are capable of swinging in two planes in case of running over uneven ground so that with the controlling means as hitherto used the swinging movement of the trackchains in the one plane only can be balanced, while the controlling means necessarily must follow the oscillation or swinging movement of the track-chains in the other plane so as to have some effect on the moving direction of the bogie or truck.

According to the present invention, the track-chain bogie or truck supported by a spherical member is provided with a lever mounted on the bogie frame supporting the load so as to transmit the weight thereof to the guiding frame of the track-chains, the said lever being adapted to be turned about a horizontal axis passing through the centre of the said spherical supportin member, and having its free end shaped to orm a head or pin for the controlling rod or rodwork to engage therewith, the construction and, arrangement of the parts being such that the centre line or axis of the pin will also pass through the centre of the said spherical supporting member.

In case of a bogie or truck of the character set forth and provided with diagonal or universal joint supports intermediate between the load frame and the bogie frame, the centre lines of the swinging axis of the lever and of axis of the pin will coincide, according to the present invention, with the corresponding centre lines of the axes of the universal joints. In lieu of the pin, however, any other suitable means such as a ball-joint or the like may be provided for the engagement'with the controlling rod or rodwork.

By constructing the controlling mechanism in the manner herein set forth the point of engagement or connection between the controlling rod or rodwork and the lever will not and cannot change its position with relation to the body of the car, whenthe bogie frame is accidentally caused to swing.

I will now proceed to describe my invention more in detail in connection with the embodiment thereof illustrated somewhat diagrammatically on the accompanying drawings, it being intended and understood that the invention is illustrated by, but not limited to the embodiment thereof so illus- (rated and described.

In the accompanying drawings forming a part of this specification and illustratin for purposes of exemplification apreferred orm and manner in which the invention may be embodied and practised, but without limit ing the claimed invention to suchillustrative instance:

Figure 1 is a view in front elevation of a track-chain bogie or truck having two trackchain guiding frames, and Figure 2 is a view in top plan thereof. In the embodiment shown the two trackchains a are interconnected by axles b with the bogie frame a mounted thereon in the usual manner. Track-chain guides frames b are provided within the track-chains a in such manner that the chains ware supported andguided thereby as they travel about,'said frames 6' also having the axles b mounted therein. Each bogie frame 0 is supported by at least two track-chain guide frames 6 and the corresponding track-chains a. The

bogie frame 0 carries, at a point midway between its two ends, a boss 0? having a spherical surface for the load frame 6 to be supported thereby. The extremities of the two shanks of the forked lever f are pivotally connected with the bogie frame a by means of horizontal pins 9 so that the lever can be turned or swung about the common axis h of the two pivots or pins 9 passing through the centre of the spherical boss 05 and which may, as shown in the embodiment illustrated, lie in the running direction of the car.

The free end of the lever f is shaped to form a head or pin 5 for connection with the rodwork of the controlling mechanism. The median line is of the lever, that is, the axis the-spherical boss 03 and crosses the axial Ito line h at right angles. Whenever the chains run over uneven ground so that the bogie will be caused to swing in the one or other direction, the head or pin 2' will remain sta- 8 tionary all times inasmuch as it cannot change its position with relation to the load frame.

What I claim is 1. In an arrangement of the character de- 10 scribed of theatype maxing afbo'gie drains situated under and univeisallye'nnstbed-ho the load frame and wherein at least tvvo track-chain uide frames snpport%e hogie frame, a for red controlling lever having the ends o'ii itshranches pivotal y connected "to the bpgie frame at points on opposite "sides 0 the universal eonnettion in sueh manner that the -longitudinal axes of such ,pivot points coincide with the correspondingrlongitu, inal axis ofthe universal connection, and a ills-ad pin on the main e d tthe lev r ada ted for association Wi hfihe controlling mec anisnn of theear and having its longitudinal axis coinciding with the "correspondg5 ing moving axis of the universal joint and intersecting the axes of the ,pivotally connected branches.
